Question about 1998 Saturn SL

1 Answer

Not stable idle but no loss of power when RPM over 1500 SES light ON steady

Very rough idle 1000-1500 RPM but not stalling and over 1500 RPM looks OK, The service negine light is ON steady.
I have a module for reading GM code that works on Transport TPI injection, would it work for that model?
Any idea will be appreciated

1993 gmc suburban rough idle, stall in reverse


Idle air control (IAC) control rpm idle during idle.

Test it on idle with ALL electrical on full force.
RPM should increase.
If RPM remain the same then IAC is question.

Increase then decrease idle when engine is cold especially


cold engine idle surge. (problem)
RPM range of surge not stated
300-700 or 800 to 1500? (range is critical to diagnosis)

bad fuel
running summer fuel in winter (running old fuel?)
needs a tune up bad, see the list in the operator guide.
idle speed controller,sticking or EGR valve same. (clean them)
location not stated, so cant guess about local air temps.?
no other symptoms, lack of engine power? etc?
was it ok last week, or better, when was the last time it was OK?
1week, 1year?
surge , causes, on a tuned engine might be:
1: too lean. so lean the ISC can not control idle. rpm low, stalling
2: too rich, flooding, stalling, spark plugs foul (look at them)
3: weak compression in 1 or more cylinders.
4: bad spark.
5: air leaks, in the plenum causing , ISC to lose control.
why high RPM?

especially?
well that means it fails hot too.
and there is a simple tests. for hot surge.
is engine fully hot? 180F and holds solid there?
say rpm is about 800
and you turn on head lights, heater fan and (not AC) and defrost.
the RPM must hold or the ISC is failing.
ISC -= idle speed controls. (all EFI has this function)

1991 Chevy Caprice has a mild miss fire and stall at low rpm: This is my latest update: I checked and cleaned the EGR,PCV,IAC valve, M.A.P sensor and Throttle body(bore/butterfly). with carb cleaner....


Do you have the idle speed turned up to keep it from dying? Because it is high. Check engine light on? Have you checked for vacuum leaks at the gasket under the throttle body? How does the car run under acceleration? You might have a worn distributor shaft.

Look at replacing idle motor on throttle body, it is a electrical solenoid $70

Rough idle then stalls


Vacume leak or bad idle motor. With the car in park and running with the hood open listen for leaks moving your hand around the different hoses looking for a change in the sounds that you hear. The idel motor also makes the car idel up to 1500 RPM or so right at start-up then idel down, If it doesn;t the idel motor is likly. Check engine light is on when running? Test for codes, Follow code test charts don't skip any steps!.

I don't have steady rpm between 1000 and 2000 rpm


Pros
  • The EGR valve is vital to your car's emission controls.
Cons
  • When the EGR valve goes bad, it must be replaced.
Description
  • EGR Valve = Exhaust Gas Recirculation Valve.
  • The EGR valve controls formation of noxious emissions.
  • Rough idle and poor acceleration can be caused by a faulty EGR valve.

Sounds like it could be the throttle position sensor.
